The production of $J^{ PC} = 1^{ ++},0^{ -+}$ and $2^{ -+}$ mesons in double tagged $e^+e^- \to e^+e^-R$ is calculated and found to have the same polarisation and dynamical characteristics as observed in $pp \to ppR$. Implications for the spin structure of the Pomeron are considered. Production of $0^{ ++},2^{ ++}$ mesons in these two processes may enable the dynamical nature of these mesons to be determined.
